What is good hygiene for Calc formulas?

I’m fairly new to LO.

I have a spreadsheet that has 30,000 lines of data.

It’s got very slow when flitering and sorting.

Are there any hygiene principles I can know to reduce the hang? Or is it simply the size?

And generally should I avoid formulas that use a whole column, like SUM(A:A), or does Calc exclude empty cells when processing such a formula?

Thank you.

Does the problem persist if you use the latest version (LO 24.8)?

It’s worse :crazy_face:

EDIT: I have found the ‘recalculate’ options and have switched to manual recalculation. This has helped when cutting / pasting, and a bit when filtering / sorting.
